This study sought to assess the spine\u2019s mobility while wearing three different orthopedic braces while performing basic tasks. Ten healthy subjects were enrolled. Three Inertial Measurement Units (IMUs) were attached superficially along the spine at approximate levels: cervical (C7), between thoracic (T8) and lumbar (L3), and sacrum. The angle between sensors was monitored to provide data on the sagittal profile. In addition, the displacement of the spine\u2019s longitudinal axis was measured (rotation). There are three types of orthopedic braces: the semi-rigid Hohmann corset, the Jewett brace, and the Thoracolumbar Fixed Spinal Orthosis (TLSO). Four tasks were monitored: standing, sitting, walking, and picking up an item from the floor with one hand. All braces provided a similar level of stability in both the sagittal plane and rotational axis while lifting an object. On the other hand, while walking and sitting, the TLSO was the only orthosis providing a statistically significant rigidity in the sagittal plane. When performing a more voluntary task, the measured rigidity of softer braces was significantly increased when compared with more involuntary tasks. A certain degree of motion restriction with spinal orthoses may come from the feedback pressure, which stimulates paraspinal muscles to contract and thus increases the overall rigidity of the trunk.<\/jats:p>","DOI":"10.3390\/ijerph192416515","type":"journal-article","created":{"date-parts":[[2022,12,9]],"date-time":"2022-12-09T02:20:31Z","timestamp":1670552431000},"page":"16515","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Evaluation of Movement Restriction of Spinal Orthoses Using Inertial Measurement Units"],"prefix":"10.3390","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9845-4961","authenticated-orcid":false,"given":"Justyna","family":"Fercho","sequence":"first","affiliation":[{"name":"Neurosurgery Department, Medical University of Gdansk, 80-214 Gda\u0144sk, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0817-7989","authenticated-orcid":false,"given":"Micha\u0142","family":"Krakowiak","sequence":"additional","affiliation":[{"name":"Neurosurgery Department, Medical University of Gdansk, 80-214 Gda\u0144sk, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6386-3589","authenticated-orcid":false,"given":"Rami","family":"Yuser","sequence":"additional","affiliation":[{"name":"Scientific Circle of Neurology and Neurosurgery, Neurosurgery Department, Medical University of Gdansk, 80-214 Gda\u0144sk, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1904-6773","authenticated-orcid":false,"given":"Tomasz","family":"Szmuda","sequence":"additional","affiliation":[{"name":"Neurosurgery Department, Medical University of Gdansk, 80-214 Gda\u0144sk, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Piotr","family":"Zieli\u0144ski","sequence":"additional","affiliation":[{"name":"Neurosurgery Department, Medical University of Gdansk, 80-214 Gda\u0144sk, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dariusz","family":"Szarek","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Marciniak\u2019s Hospital, 54-049 Wroc\u0142aw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4703-1624","authenticated-orcid":false,"given":"Samuel D.","family":"Pettersson","sequence":"additional","affiliation":[{"name":"Scientific Circle of Neurology and Neurosurgery, Neurosurgery Department, Medical University of Gdansk, 80-214 Gda\u0144sk, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6781-7013","authenticated-orcid":false,"given":"Grzegorz","family":"Mi\u0119kisiak","sequence":"additional","affiliation":[{"name":"Institute of Medicine, Opole University, 45-052 Opole, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,12,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Weppner, J.L., and Alfano, A.P.
